Add queue auto-discovery support for BullMQ meta keys

[Copilot]

Queue auto-discovery currently relies on :id keys, which causes modern BullMQ queues to be missed when only :meta exists (e.g., worker/queue initialized before any jobs). This change extends discovery to include :meta keys while preserving existing queue parsing and typing behavior.

• Discovery behavior

  • Scan Redis for both queue key patterns:
    • *:*:id (TYPE string)
    • *:*:meta (TYPE hash)
  • Normalize discovered :meta keys to canonical :id queue identifiers so downstream logic remains unchanged.
  • Deduplicate queues found by both key types.

• Queue key parsing hardening

  • Replace regex-based queue key parsing with delimiter-based parsing (lastIndexOf) for id|meta suffixes.
  • Keep the same extracted queue identity (prefix, name) semantics used by discovery and warning paths.

• Focused coverage

  • Add targeted tests for:
    • discovering a queue when only :meta exists
    • avoiding duplicate queue entries when both :id and :meta exist

// discovery now checks both key families
SCAN ... MATCH "*:*:id"   TYPE string
SCAN ... MATCH "*:*:meta" TYPE hash

// normalize meta key to canonical queue key
bull:emails:meta -> bull:emails:id

Pull request overview

Extends Bull/BullMQ queue auto-discovery so BullMQ queues are found even when only :meta exists (e.g., before any jobs create :id keys), while keeping downstream queue handling based on canonical :id identifiers.

Changes:

• Add :meta (TYPE hash) scanning alongside existing :id (TYPE string) scanning, normalizing :meta → :id and deduplicating results.
• Replace regex-based queue key parsing with delimiter-based parsing (lastIndexOf) supporting both id and meta suffixes.
• Add tests covering meta-only discovery and de-duplication when both key types exist.
